FILM-'HOLDING DEVICE.

Application filed December 1S, 1916.

`and useful Improvements in Film-Holding Devices; andl do hereby declare the folloiving to be a full, clear, and exact description fofthe invention, such as Will enable others skilled in the art to Which it appertains to make and use the same.

l--'My invention relates to photography, and more especially .to Work-handling devices in Huid-treating apparatus. To the above end the invention consists of the novel devices Vand combinations of devices hereinafter described and defined in the claims.

In` the accompanying drawings, which illustrate the invention, like characters indivcate likeparts throughout the several views.

Referring to the drawings, Figure 1 is a perspective view of a liquid holding tank with a portion thereof broken away to expose the film holding device supported therein;

Fig. 2 is a perspective view of a supporting bracket 'for holding the film holding de- Vvice in a loading position, the films being vpdiagrammatically shown byy means of broken lines; and

F ig.1 Sis a fragmentary vievv corresponding to Fig. 2, with the exception that the pin Ehas been'partlyvvitlidraivn and in position 'to pierce' a film.

' ing device comprises a main or upper section 5, Whichis complete in itself, and one or more supplemental sections 6 supported,

`the one from the other and the uppermost ythereof from the 'main section 5.

The main section 5 is made up of a rod 'V17 having its ends bent laterally to afford a pair o-f arms 8, the free ends of which are bent laterally and outward to affordfingers 9. :These-noers 9 are arranoed to rest on the rim of the tank loii opposite sides there- 'of and support the rod 7 therein by means of its arms 8. 1' lingers 9 are quite long, so as to support the lilm holding device'ivithin tanks va "ying 1t will be noted that the 'considerable in Width. A tubular body f member 10, folded from a sheet of metal, has

permanently and rigidly connect said body member to the rod 'l'. Transversely cut'iii the body member 10, is a multiplicity (as shown tivclve) of iilm receiving slots or seats 11. rfi long sharp pointed pin 12 having a head 13 is adapted to be inserted through the body member 10 to pierce and hold i'ilms 141 as they are successively inserted in the slots 11, as indicated in Fig. 2.

The supplemental sections 6 are-identical with the main section 5, With the exception of the fingers 9, and the parts thereof are designated by like reference numerals. T he ends of the arms S of the supplemental sections 6 are bent to forni hooks 15 adapted to interlock with the rods 7 just inside of the arms 8, and suspend the uppermost supplemental section 6 from the main section 5 and the other of said supplemental sections, the one from the other, as shown in Fig. 1. Obviously, the engagement of the hooks 15 with the arms 8 holds the several sections detachably'interlocked and .against endwise movement, ivith respect to each other. By taking hold of the iingers 9, the 4entire film holding device may be let down into the tank 11 or removed therefrom.

Thilo loading the sections 5 and 6 with films 11, 1 provide a supporting bracket 16, as shown, in the form'of a board set vertically edgeivise and rigidly held in position by a pair of angle irons 17 secured to a table or other suitable support. `rThe ends'of the bracket 16 are notched at 1S and 19 to receive the arms 6 of a section, Whilethe body niember 1U thereof rests on the upper longitudinal edge of said bracket. lt will be noted that vthe rear prongs of the bracket 16, formed by the notches 18 and 19, are longer than the front prongs thereof and that the notch 19 is somewhat deeper than the notch 18. ln positioning one of the sections 5 or 6 on the bracket 16, a horizontal endivise movement thereof toward the right is necessary to carry the left hand arm 8 into the notch 19 and jdien a reverse movement of the section will carry its riOht hand arm 8 into the notch 16. By making the rear prongs of the notches 1S and 19 longer than the front prongs thereof, it makes the entering of the arms 8 in the notches 18 and 19 an extremely simple matter. Villien the right hand arm S is in the bottom of the notch 1S, the left hand arm 8 still remains in the notch, thus securely holding the respective section against lateral separation yfrom the supporting bracket 16, as shown in Fig. 2. It is also important to note that when one of the sections 5 or 6 is positioned on the supporting bracket 16, t ie head of the pin l2 is at the right of the operator.

In loading one of the sections 5 or 6, after the same has been positioned on 'the supporting bracket 16, as shovvn in Fig. Q, the pin 1Q is Withdrawn, as indicated in Fig. The operator, standing in front of the support-- ing bracket 16, takes hold of the head o 't the pin 1&2 with his right hand and uses his left hand to successively place the films .1l--

in the slots 11 Working from the right 'to-- Ward the left. As each film l-l is placed in its respective slot or seat 11, the operator gives the pin 12 a step of movement sufficient to pierce and hold the film. The engagement of the right hand arm 8 with the bottom of the notch 18 holds the respective sections 5 or 6 against endwise movement, during the piercing of the films 14C by the pin 12. The left hand portions of the body member 10 at each slot 11 forms a rigid surface against Which the films 141 bear, While being pierced by the pin 12, thus preventing the same from being torn or mutilated.

In loading the sections 5 and 6, the seetion 5 should be loaded first, removed from the supporting bracket 16 and temporarily hung up by its fingers 9 on pegs or other supporting means, not shown. One of' the supplemental sections 6 is next loaded and hung from the section 5 by means of inter'- locking its hooks 15 therewith. If other supplemental sections 6 are loaded, they are hung, the one from the other, as shown in Fig. 1. After sufficient sections have been loaded to reach substantially to the bottom of the tank 4, the same are lifted by the lingers 9 from the supporting pegs and deposited in the tank 4t.

From the above description, it is evident that after the films are once secured to the film holding device, they need not again be touched by hand during the developing, fixing, Washing and drying thereof. By means of the finger pieces 9, the device may be lifted from one tank to the other, during the developing', fixing and Washing, and then hung on tanks or other supports, While the films are drying. After the films are dry, the lowermost section 6 is detached from the other sections and the films removed therefrom by withdrawing the pin 12. By repeating this operation, the films may be very quickly removed from the device.

It is, of course, understood that one or more sections may be used at a time and as many film holding devices placed in the tank, at the same time, as the tank Will.

hold. By means of the differentsections, the films of different packs may be kept together and it is only necessary to mark one film on each section, for the purpose of identification. The above described invention, vfhile extremely simple and of comparatively small cost to manufacture, has, in actual usage, proven highly efficient for the purpose had in view.
